PCE superplasticizer is the newest generation superplasticizer in domestic and abroad.
Comparing with PNS and other superplasticizer, PCE superplasticizer has many characteristic
advantages in technology and performance as following:
(1) low dosage, high rate of water reducing;
(2) keep concrete good slumption retention;
(3) good compatibility with cement;
(4) small shrinkage of concrete to keep the stability of volume and durability;
(5) environmental in production and usage. Base on above advantages, PCE superplasticizer attract the attention from engineering field and has been widely used in some important projects. Predictably, base on above advantages, PCE superplasticizer will be the main trend in the market.
Due to most of PCE superplasticizer is liquid and procedure of PCE powder is complex and
dangerous, PCE superplasticizer is mostly sold in liquid in market. Recently, with the
technology and procedure improved, PCE powder is common in market. the powder will be more
convenient for client in transport and use. So the powder is becoming the trend of this product.

It makes cement good dispersibility and fluidity in low dosage.
When dosage is from 0.12% to 0.22%, the cement paste fluidity grows obviously.
There is no loss of fluidity within 1 hour in cement paste.
The fluidity of PCE powder is 2 times of other superplasticizer in market.
It is homologous between water-reducing rate of motar and fluidity of cement paste.The more fluidity of cement paste, the more water-reducing rate of motar.
Water-reducing rate increases fast and high when the dosage increase. When the dosage is same,the water-reducing rate of PCE powder is 35% higher than that of other superplasticizer in market.
Due to the influence from the admixture and sand coarse aggregate, Water-reducing rate in concrete is different from that of motar.When the the admixture and sand coarse aggregate are in favour of the concrete flow, the water-reducing rate of concrete is higher than that of motar.
It has antifreezing performance when temperature is above -5ºC. So it can be used in antifreezing concrete.

with PCE powder is lower ,Initial setting time prolong 60 minutes , final setting time
is similar, air content is controlled in 2-4%.
The recommend dosage of superplasticizer for concrete: 0.1-0.25% base on cement quantity.
Solid contents of PCE powder is 98%. Normal dosage is 0.12%-0.3%. when dosage is 0.06%, it
has 12% water reducing rate and 23% strength growth, this beyond the performance of common pumping agent in market. when dosage is 0.1%, performance beyond that of PNS and Melamine. But when dosage is below 0.14%, its good performance is not obvious. When dosage is above 0.20%, it is excellent in concrete fluidity and pumping performance. Therefore, the best dosage is recommended as 0.12-0.24%; when making concrete with high grade, big dosage of flyash or superfine slag powder or other special requirements, dosage can be expanded to 0.3-0.5%. Test state that there is no cohesion and bleeding in concrete even the dosage expand to 0.5%, and its water-reducing rate still increase . But air content increase, setting delay, strength decrease.
At present, most PCE powder in market are produced by process of sparying and drying. So they
have some defect: its 5% separant,3% moisture result loss of effective constituent and performance in use.
We break the routine of producing PCE powder. It First use the technology of thermosynthesis which save the producing cost in a lot, without separant, with high purity of 98% solid contents. In performance, high purity guarantee the low dosage, more effective constituent guarantee the better slump retention, those save the cost for client.
(1)According to the design of concrete, adjust quantity the water or sand to make sure the slumps,
strength, setting all to meet with requirements base on the required dosage of admixture.
(2)It apply to concrete with high performance ,strength and fluidity. When make C50 concrete,
it should choose the suitable material according to relative technology rule and confirm the
suitable mixing technology base on enough test data. To make sure the fluidity of concrete can
meet with the requirements of engineering, the strength of concrete should have surplus .
(3)This product can be added into concrete together with water which is used in mixing. but it
will get better performance if mix it with water firstly.
6,Safety and Attention:
(1)This product is alkalescence solid without toxic, corrosiveness and pollution. It is unedible.
when it come to body and eye, please wash it in clean water. When there is allergy for some body,
please send the person to hospital rapidly for cure.
This product is storaged in paper barrel with PE bag inner. Avoid rain and sundries to mix in.
Quality guarantee period is 12 months
Package: Paper-Plastic lamination package with PCE inner.
